the answer is 25%
25 PERCENT !!!!!!!!!!!!!!!!!!!
To determine the probability that the offspring will be a short plant, we need to use the principles of Mendelian genetics.
In this case, we have two heterozygous tall pea plants being cross-pollinated. The tall trait is dominant over the short trait.
Let's represent the genotype of the parents as follows:
Parent 1: Tt (Tall)
Parent 2: Tt (Tall)
To determine the possible genotypes of the offspring, we can use a Punnett square:
| T | t |
-------|----|----|
T | TT | Tt |
t | Tt | tt |
As shown in the Punnett square, there are four possible combinations of alleles: TT (tall), Tt (tall), Tt (tall), and tt (short). Out of these possibilities, only one combination results in a short plant (tt).
Therefore, out of the four possible combinations, one combination leads to a short plant. This means that there is a 25% chance that the offspring will be a short plant.
So, the correct answer is 25%.
